(54) Inductor gap spacer


(57) An inductor (10) comprises a ferromagnetic or ferrimagnetic core (12) with a reluctance gap (16), a plurality of conductive windings (18) disposed about the core (12), and a spacer (20). The spacer (20) separates the conductive windings (18) from the core (12) in the immediate vicinity of the reluctance gap (16), such that the conductive windings (18) are substantially unaffected by fringing flux from the reluctance gap (16).
